HYDROCARBON-BRNER.

Specification of Letters Patent.

Patented haar. 13, 1917.

Application filed November 29, 1915. SerialNo. 64,018.

To all whom t may concern:

Bc it known that lf, WILLmM THOMAS VOOD, a citizen of the United States of America, and a resident of Nashville, county of Davidson, and State of Tennessee, have invented certain new and useful Improvements in l-lydrocarbon-Burners, of which the following is a specification.

The main objects of this invention are to provide an improved form of hydrocarbon burner; and to provide such a burner having an improved construction and arrangement of the fuel vaporizing and mixing chambers.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which:

Figure 1 is a top plan witha part of the burner casing broken away.

Fig. 2 is a side elevation with the burner casing in section.

Fig. 8 is a horizontal section of the supply pipes and control valves.

In the construction shown in the drawings, a burner chamber 1 is formed by a casing comprising a pair of castings 2 and 8 secured together by screws 4i, which pass through suitable registering lugs k5 on said castings. Fuel vapor may be projected into the burner chamber for ignition therein through tangentiallv disposed tubular mixing chambers or passages 6 and 7, which communicate with said burner chamber.

The lower or base part 3 of the burner casing is provided with an annular series of air supply apertures 8, and with a comparatively large centrally located opening 9. The burner casing is supported by an annular ring 10 of suitable material, such as sheet iron, attached 'to a depending flange 11 on the under side of casing 8.

Fuel may be supplied to the burner by pipes 12 and 18 which may communicate with a common supply pipe 14, and which are separately controlled by valves 15 and 16 respectively. rihe pipes 12 and 18 pass through the support under the base 8, up through the centrally located opening therein, and terminate in relatively large spherical fuel vaporizing chambers 17 and 18 respectively. These vaporizing chambers are preferably located adjacent to the tangential mixing chambers 6 and 7.

Vapor formed in the chambers 17 and 18 is conducted out through the burner casing by suitable pipes 19 and 20, which terminate in nozzles 21 and 22 respectively, located in front of and in line with the mixing chambers 6 and 7.

Means for initially heating the fuel vaporizing cl ambers, vapor-conducting pipes, and nozzles v)are provided, and comprise shallow pans or trays 28 mounted under these respective parts and adapted to, receive a. small Quantity of fuel.

in the operation of the device, the pans or trays 28 are partly filled with fuel which is then ignited. r[he blaze from this fuel heats the vaporizing chambers, vapor-conducting pipes, and nozzles, and when the temperature of these parts is raised to a sufiicient degree, fuel is allowed to pass into the supply pipes 12 and 18 by means of the valves and 16. Such fuel upon reaching the chambers 17 and 18 is retarded in its flow, thus giving it time to become vaporized through contact with the heated walls thereof, and the vapor is conducted by pipes 19 and 20 to the nozzles 21 and 22. As the gaseous vapor passes through the tangentially disposed tubular mixers, it is combined with air in the usual manner.

The tangential arrangement of the mixers with respect to the burner gives a rotary movement to the flame, which insures a thorough mixing of the hydrocarbon with the additional air supplied by the central opening 9 and the air inlets 8.

rilhe vaporizing chambers 17 and 18 are adjacent tothe mixers and in the vortex of the whirling iiame, and are consequently maintained at a high temperature.

Although but one specific embodiment of this invention has been herein shown and described. it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

l claim:

1. The combination of an open topped bowl shaped casing, one or more mixing chambers directed tangentially into said burner casing, a vaporizing chamber located within said bowl shaped burner casing and connections for directing the gas from said vaporizing chamber endwise into the mixing chambers so as to produce a whirling fiame.

2. A device of the class described, comprising an open topped bowl-shaped burner casing, a fuel vaporizing chamber located in said burner casing, means for supplying fuel to said chamber, and means for projecting the vapor formed in said chamber into said burner casing tangentially thereto for producing a whirling liame.

3. A device of the class described, comprising an annular burner casing having a plurality Vof tangentially .disposed mixers opening thereinto, a plurality of fuel vaporizing chambers located in said burner casing, fuel supply pipes communicating with said vaporizing chambers, and vapor conducting pipes passing out of said burner casing and having nozzles located in front of said tangentially disposed mixers, all being arranged to produce a whirling flame at said burner casing.

4E. A device of the class described, comprising an annular burner casing having a plurality of tangentially disposed mixers in the side thereof and having an annular series of air supplying apertures in the bottom thereof, said casing also having a relatively large centrally located air inlet opening in the bottom thereof, a plurality of fuel vaporizing chambers located in said burner casing above said centrally located opening, fuel supply pipes communicating with said vaporizing chambers, and vapor conducting pipes connected to said vaporizing chambers and provided with suitable nozzles for projecting the vapor formed in said chambers into said mixers. n

5. A device of the class described, comprising an open-topped bowl-shaped burner casing, a globular fuel vaporizing chamber located in said burner casing, means for supplying fuel to said chamber, and means for projecting the vapor formed in said chamber into said burner casing tangentially thereto for producinga whirling flame around said globular chamber.

6. A device of the class described, comprising an open-topped, bowl-shaped burner casing, a globular fuel vaporizing chamber located in said burner casing, said chamber 4 having relatively small inlet and outlet con# nections, means for supplying fuel to said chamber, and means for projecting the vapor formed in said chamber into said burner casing tangentially thereto for producing a whirling flame around said globular chamber.

Signed at Nashville this 23d day of November 1915.
